Panel view plus and trends

This is my first pass at using trends in a PV+. So far so good I have my trend up and working, my question: is there a way to trigger the trend to start and stop?
I have a SLC 5/05running the program and we are doing a pressure test on each part, I only want to trend the prssure test it self. I would also like to figure out a way to automatically print the results after each test. Any help or suggestions would be greatly appreciated.

1- you can make Pause button to pause your trend data display by creating new pause button and link it to your trend
2- create print display button to print your display screen with all monitored data at the time you make any tests.
